Will be much better XP at 65, for sure. Sand giants (south) had the largest wing, and could support several static groups without running out of mobs back in the day. Tornado (north) were always the last ones camped. Also did some soloing and grouping in the courtyards (run across portals at the far end of any wing). I don't imagine any of those loots are worth anything as loot, but might be for tribute or tradeskillers.
